Page 5: Chapter 3 Description
The TEC lockout can easily be bypassed by setting an on-board jumper. The LDM9T mount has a compact design, with a low speed fan to increase the cooling capacity, and still offers the features typical to our other products. The mounting options include multiple #8-32 (M4-0.7 on the /M version) mounting... -

Page 7: Chapter 4 Setup
Most laser diodes are three pins with the case tied to one of the laser pins and also to one of the photodiode pins. The other laser and photodiode pin will be isolated from the case. The LDM9T was designed to operate the laser case at ground potential therefore this common pin will be inserted into either the 9 o’clock or the 3 o’clock position of the... -

Page 11: Chapter 5 Operation
5.2. RF Modulation The LDM9T has an RF input for modulating the laser with an external RF source from 200 kHz to 1 GHz. This is a 50 Ω input that is AC-coupled directly to the laser through the Bias-T network. To calculate the desired RF power to modulate the laser, determine the amount of modulating current needed from the laser manufacturer’s data sheets and use the following calculations:... -

5.4. Active Cooling System The LDM9T incorporates a fan in the heat sink to improve the heating/cooling capacity of the mount. The fan speed is actively controlled to provide the best overall performance when high power loads are installed and to keep noise and vibration to a minimum when light loads are applied. -

Page 13: Safe Operating Area (Soa)
The safe operating area for the mount is basically the area at which the thermal power of the laser diode can be removed and dissipated by the LDM9T. How much power the mount can dissipate depends on a number of factors, ambient temperature and set point temperature being the most important. -

Page 15: Chapter 6 Making Safety Interlock Connections
Chapter 6: Making Safety Interlock Connections Making Safety Interlock Connections The LDM9T is equipped with a Remote Interlock connector located on the side panel. In order to enable the laser source, a short circuit must be applied across the terminals of the Remote Interlock Connector. In practice this connection is made available to allow the user to connect a remote actuated switch to the connector (i.e., an open door indicator). -
